3 ways to lower CT radiation dose across the hospitalMay 24, 2019 -- A hospital-wide quality improvement project effectively lowered CT radiation dose by nearly 20%, report researchers from Seattle. They detailed how three initiatives enabled them to achieve this dose reduction in an article published online May 21 in the Journal of the American College of Radiology. Discuss

Can DBT replace FFDM?May 24, 2019 -- Can digital breast tomosynthesis (DBT) replace full-field digital mammography (FFDM)? Yes, especially if wide-angle DBT is used, according to a study published in the June issue of the American Journal of Roentgenology. Discuss

AI can optimize risk stratification of thyroid nodulesMay 24, 2019 -- An artificial intelligence (AI) algorithm improved the specificity of the American College of Radiology Thyroid Imaging Reporting and Data System, while also making the thyroid nodule risk-classification system easier for radiologists to use, according to research published online May 21 in Radiology.
